All hearing aids use the same basic parts to bring sounds from the environment into the ear and make them louder. Most hearing aids are digital and all work with a traditional hearing aid battery or a rechargeable battery. If you think you might have hearing loss and could benefit from a hearing aid, see your doctor, who may refer you to an otolaryngologist or audiologist. In addition, some people may prefer the open hearing aid because their perception of their voice does not sound “stuffy”.
Volume Control: Many digital hearing aids don't have a volume control or have a very limited volume control. In general, the ITE aids are not used by young children because the shells need to be replaced frequently as the ear grows. Some private insurance policies cover part or all of the cost of hearing aids; check your policy to be sure. As the code also includes information about the pitch or volume of a sound, the aid can be specially programmed to amplify some frequencies more than others.
Directional microphones hold great promise for making it easier for people to hear a single conversation, even when they are surrounded by other noises and voices. The hearing aid receives sound through a microphone, which converts sound waves into electrical signals and sends them to an amplifier. Function Switch: Used to turn the hearing aid on and off and can be used to toggle between listening programs. Researchers funded by the NIDCD are also studying how hearing aids can improve speech signals to improve comprehension.
Pairing a hearing aid with other assistive hearing devices can improve some people's speech comprehension by reducing or eliminating background noise. Some headphones have a volume control (increase or decrease the volume of the sound) or a program button. If your hearing aids have controls, you may have a volume control, a program button, or a function switch. Medicare does not cover hearing aids for adults; however, diagnostic evaluations are covered if ordered by a doctor to help the doctor develop a treatment plan.
An audiologist can program help with a computer, and you can change the program for different listening environments, from a small, quiet room to a crowded restaurant or large, open areas such as a theater or stadium.
